How to use Rails on Google App Engine (Thanks to JRuby)
Two days ago, Google announced the release of Java support on its App Engine service (a system that allows you to run Web apps on Google's infrastructure). And.. what runs on Java that we care about? JRuby!
It took JRuby guru Ola Bini just a day to work out how to get JRuby and Rails working on App Engine using the Java support. So, in a round about way, App Engine now supports Ruby too..
If you're not already familiar with getting a Rails app running on JRuby, it's not going to be a walk in the park, but even experienced JRubyists might need to do a double-take, as you're not going to be using ActiveRecord and the authentication system (using Google's user service) is a different kettle of fish.
